I for one don't really care much about memory consumption because I have plenty.
What worries me is how much CPU hungry an AV is, and NOD32 is still the lightest I've tried in that area. It's like a breath of fresh air when you uninstall your old AV and replace it with NOD32, it basically gives your PC it's powers back

Hmm....Are you saying that the more malware definitions in the database, the more heavy an AV gets?

Then it means:

More Malware Definitions eventually lead to bigger incremental or cumulative update size.
More Malware Definitions means the NOD32 Scanner has to scan for more malware in files, which means more time is taken.
More malware definitions means the AMON/IMON/DMON has to protect against more kinds of threats, which means it has to occupy a larger footprint in memory.

So eventually, updates will become very big, and programs very heavy and slow. Is that true?

Hey,
When I started using NOD32 (2.1) it was using a very small amount of memory around 10-12k.

With the new versions it's using around 16-25k, I know that it may differ between computers but are there any plans to make the new version lighter?

Come on lets get real here 16-25k(approx 21k on my pc) is still "light",when you 1st used Nod most pc's prob had only 64-128mb(power user!!)of memory so its all relative,nowadays 1gb(and above) is common! %age wise nowadays Nod probably uses less of most users available memory than it did in days gone by

I've used; NAV 2005, KAV 5, AVG free, and am now using Nod32. Nod32 is by far the 'lightest' of those I have used (I use a 6 year old, windows 98 PC with limited RAM). AVG comes pretty close to Nod in terms of 'lightness' on my computer, KAV was ok, NAV 2005 crashed it

As Heuristics improve, we won't need so many signatures. NOD presently has the best heuristics, but I iamagine that it will keep getting better.

But if it keeps increasing its Memory usage, in the future it would use 40k...

Vendors like Frisk and drweb has less memory usage
And many vendors these days are improving their performance... Just thought Eset did so too

Even 40k aint too bad as long as protection is "worth it" depends on what trade offs are important to you:- protection against system impact ,as long as impact remains low(memory+cpu load!) and protection high I for one am not bothered if others are lower in memory usage,I choose an AV for protection as the first consideration

I can't imagine than an antivirus would be continually loading and unloading virus signatures when scanning files. I can only agree with the first out of the three points, the rest is untrue.

Don't worry, my earlier post was a half-joke.

However, I do realise the whole database is loaded when an On-Demand scan is run, but since there is more malware to scan for after every update, wouldn't it take a few more CPU cycles to scan for additional malware code?

Of course, I'm assuming such diferences would be quite negligible, and not noticeable till the next 1000 years, that is if you still kept your Intel Pentium 4 by then

I was an F-prot user prior to becoming a NOD32 user, F-prot was light and ran very well on my laptop, NOD32 runs equally well even though nod32krn.exe is 20,116 and nod32kui.exe is 2,168 ram usage at the moment, cpu percentage is cycling at 5-8%, I find this extraordinary in the performance area for an antivirus, my onboard ram is a single 512 stick and my laptop doesn't miss a beat, plenty of ram for everything I do, ram usage is not that important in my opinion, it's easily increased if needed, cpu cycles, now that's another story...

If you are in a computing environment where memory is at a premium, you can disable the NOD32 Control Center (filename: NOD32KUI.EXE) so it no longer runs automatically each time the computer starts up. This will save you about 2MB of memory (±0.5MB).

You will still be able to access the NOD32 Control Center via the Start Menu, if you want to view or change NOD32's settings.
